Steps to be Followed
Start by drawing a rough sketch of the raised bed, as it helps you decide the materials needed to build one. In most cases, a 3 x 6 feet bed should be ideal for most seasonal plants. Height could be between 1 to 3 feet.
Using strings as markers, mark the perimeter of the bed. Clear the soil of weeds by digging up the soil a few inches. This will loosen up the soil, and help you ensure a good, leveled base. Dig half feet trenches all around the marked perimeter, and start building. If using wooden frames, make sure they are pressure treated with appropriate chemicals.
Avoid using chemicals like creosote or pentachlorophenol, as they leach chemicals into the soil and damage your plants. Fix the frames (ready-made or sawed by you) along the trenches, and join the ends with building nuts and bolts. If you want concrete bed, follow the method of laying the blocks, bricks upon each other by layering and cementing them.
Good soil is essential for healthy growth.are aware of. A raised bed allows us to change the soil conditions drastically, and in certain cases, to suit the requirement of specific plants. If one does not have good garden soil, bring in additional soil to fill the raised bed.
This soil should be a combination of light weight, humus-rich soil mixed with organic composite, and some part sand to ensure good drainage. Heavy or clay soil will stagnate water, causing more harm than good to your plants.
One of the prominent advantage of raised garden beds is the avoidance of soil compaction. One can never really move around the garden without pressing the soil down. As plants can be easily accessed, weeding, pest control, mulching, and watering can be done without worrying about the back.
